The plunger is then moved upwardly and the detachablesupporting block 30 removed and the next'sized supporting block 31 inserted, the same die member being preferably connected to the substituted supporting block 31f The in crease in depth of the supporting block3l is sufiicient to provide for the succeeding bend ing operation in forming the flange to the position shown in Fig. (3. "The final bending of the edge to form theilange occurs when the largestsupporting block 32 is inserted in the reciprocating plunger with the die mem ber connected thereto, the latter being caused to move downwardly when the machine is operated to form the finished flange, as shown in Fig. 7. In each of the successive operations the same movable die member may be I used, although in some cases it may be found desirable to utilize die memhers'ot varying lengths which, when succ ssively used, will produce the same progressive bending of the work to form the flange. This latter constructionot die member is set forth in my co-pending application bearing Serial No. 851,087 filed as of even date herewith.

In Fig. 10 of the drawings an embodiment of my invention is disclosed inwhich the article 0. is supported upon the exterior thercotby means o'trollers 7, the hinge to be formed being an outside or exterior one, as shown. The same arrangement of'rela-' lively fixed and coacting nicinbers is utilized and the substitution of varying sized supporting members torthe movable dieis effected. I

In all other respects the adaptation of my inventionto Torin outside flanges upon curved orcylinder-like objects of a hollow'inetallic nature is the same and a detailed description thcreotwill not be given.

A machine constructed in accordaiicewith my present invent-ion provides a coinpara-,

tively simple apparatus inswhic'h relatively deep flangescan be producedwithout straining the punch or buckling the material, it being obvious that the yielding character of the supporting rollers permits their remaining in contact with the article between the point o't' bending and the relatively remote point at which the article is held from the exterior. It will also be observed that the several parts can be inexpensively constructedand coii'iparatively large quantities oi articles flanged in a minimum amount of time.
